You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding?

Cysteine residues are involved in disulfide bridges that helps to form tertiary structure in a protein

Explanation:

The tertiary structure of a protein will have a single polypeptide chain backbone with protein secondary structures. The interactions and bonds of the side chains within a protein determine its tertiary structure.

The cysteine forms the disulfide bridges and they link the fragments within a polypeptide chain. Sometimes those fragments are located very far from each other with respect to their primary structure. So, the tertiary structure is the three dimensional shape of a protein.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
